MULTIPLE-CYLINDER PUMP.

Specication of Letters Patent.

Patented Sept. 3, 1912.

To all whom. it may concern.'

Bc it knownthat I, WnmIAM H. NEW- I naoimri, a citizen of the United States, residing at the city of Lansing, county of Ingham, and State of Michi an, have invented certain new and useful mpro'vements in Multiple-Cylinder Pumps, of which the: following is a specification.

This invention relates to improvements in multiple cylinder pumps.

My improvements are especially desi ed; by me for use in spraying machines w ere: a light, compact pump isdesired, and atf the same time one capable of sustainingi high, uniform pressures, although it is deff; sirable for use in various relations.

The main objects f thisI invention aren' first, to provide an improved multiple cylin der pum which is verycompact and one in; which t ie working parts are eectively= balanced. Second, to provide an improved multiple cylinder purnpwhich is simple and economica in structure and well adapted4 for hi h pressure service.

Furt er objects, and objects relating to' structural details, will definitely appear from the detailed descriptionto fo low.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my inventionis clearly illustrated in the accompanying drawin forming a part of this specification, in w ich:

Figure I is a plan view of astructure em` hodying the features of my invention. Fig. II is a side elevation-from the right of Fi I. Fig. III is a side elevation from the left of Fig. II. Fig. IV is a detail horizontal section takenona line correspondin to line' 4 4 of Fig. II, the bearing pedestalzs 3 and 30 being removed. Fig. V-is a, detail'vertical' section taken on a linecorresponding to the broken line 5--5 of Fig. IV, the base being omitted. Fi VIIis-a etail vertical -sectoni takenon .a in'e. corresponding to line 6' -6 of Fi JV, 'showin the arrangementofla pairv o 'the inlet va ve casin'gs In the drawing",l 'Amilai"l reference characters v",refer, to, similar parts throi'ighfcni'ltf,tluie several views,"` and i, the.. sectional," views" are I taken-looking -in 1the direction'l lof. the little 1' in the. body so'that .the cylinders Referring to the drawing, the base 1 is inthe forni of a rectangular frame provided with feet 2 for the attachment of the base. A yoke-like pedestal 3 is mounted centrally on this base, the uiper end ',of the pedestal being` bifurcate as shown. The pump body is mounted on the base beneath the pedestal, the body being provided with a cylinder for each cylinder?, an inlet conduit 5 and discharge "conduits 6.

chamber 4 The cylinders 7- are'open at each end and provided with shoulders 8 adapted to support the cylinders in openings 9 provided therefor 0 el). into-t e l-c ambers f4'. See Fig. V.. 'llhe cylinders 7 "are arranged in pairs with a cylinder' of each air at each side of the pedestal 3. 'The in et 5 is arranged between the Iairsof cylinders, while the discharge con uits 6 are arranged on the outer sides thereof;l -Eacli cylinder chamber 4"'is provided `.with 'inlet valves 10 and discharge valves 11. The valve casings for the inlet and thedischarge valves are, in the structure illustrated, formed integrally with the pump body, as are also the conduits 5 and 6. The pump body is rovided with feet 12, also ormed integraltherewith, adapted to rest upon the base. he sup 1y pipe 13 is coniectedvo tlllie inlet1 con uitb as shown ig ig. t e su i e ein arrange through one of thlpbilsepside niem'lziers whgreby it is supported. The delivery pipe 14 is connected to both of the discharge conduits.

The details of the valves illustrated not being a part of this invention, are not described herein.

The fpistons 15 are hollow to receive the ends o the piston rods 16, which are connected by the pins 17 to the coupling members 18 which are bolted to the inner ends o f the pistons. See Fig. V. To provide a simple and effective cyinder structure, the cylinders are provided with internal annular recesses 19. at their outer ends adapted to receive the packings 20 and the packing landsy 2,1." The flanged collars 22. are t readed upon'the cylinders to adjustably ,retainlthejfglandsl.' These collars serve .to, support the upper ends of the istons. The'cranl: shafts 23 are provide with cranks`24 at their ends, there being a crank lai'. each 'side ,of the'- edestah The iston lareccrinecte to these cran s by suitable crank pins. The driving shaft 25 is arranged between the-crank shafts. The bearings 2G and 27 for the driving andy-crank shafts are mounted on the members or forks of the bifurcated pedestal. On each crank shaft is a gear 2S, while the driven shaft is provided .with a gear 29 mesliin with both of the gears 28. The shaftis urther supported bythe pedestal 30 mounted on one of the side members of thebase l.: TheV cranks of each crank shaft are disposed'oppositely so that the-pum s of each pair. are alternately actuated. Tile driving connections for the two crank shafts are arranged 5 so that the cranks of one pair of pum'ps'are in their operative relation, at an` angle o 90 to those of the other pair. ,This secures a successive work 0st-roke for all of the pumps.

My improved pump is very com act although of large capacity. The wor in.

arts are effectively balanced and supportel 1`he pump is well 'adapted for use in maintaining high pressures.

Ifhave illustrated 'and descrribedffm ing', oveinents in detail in their .'pre'ferre ,emei diment and not .attempted toillustrate or describe the modifications ossible as I believe the disclosure made wil -enable'those skilled in the art to embody my. improvements-'as conditions dor taste may dictate.
